Java游戏开发 —— 坦克大战

引言：

坦克大战也是小时一个比较经典的游戏了，我在网上也是参考了韩顺平老师写的坦克大战，并做了一下完善，编写出来作为儿时的回忆吧！

思路：

创建主窗口，加载菜单及游戏面板。

在游戏面板中初始化各种参数，并建立各种功能组件。

利用线程固定刷新游戏界面。

处理各种碰撞问题

游戏结束。

代码：

本游戏用的是JDK1.8，编码UTF-8；

我这里用的IDE是Intellij Idea，新建了一个game的空项目，tankwar作为其中的一个模块（当然这个不重要，个人喜好罢了）。类比较多，TankWar.java是游戏入口类。GameFrame.java是主窗口类。GamePanel.java是游戏面板类。GameLogic.java是游戏逻辑类。先一口气把所有的代码贴上来再说。

TankWar.java 游戏入口类

本游戏并没有使用图片，都是用Java画的，有兴趣的朋友可以自己改用图片，图片素材我已经打包了。使用图片的朋友要注意一个问题，就是图片加载是需要时间的，第一次可能还未加载成功就直接刷新下一次界面了，这也是韩顺平老师那个第一次射击坦克不出现爆炸效果的原因。Toolkit.getDefaultToolkit().createImage这个方法有BUG，改用new ImageIcon(图片路径)).getImage()就可以了。
